Living with Hep C who should get treated
http://my.webmd.com/content/pages/9/1678_50488.htm?lastselectedguid={5FE84E90-BC77-4056-A91C-9531713CA348}
July 28, 2000 -- When Fran Kee learned he had been infected
with the hepatitis C virus, he decided to start the grueling,
yearlong treatment process, even though doctors said he could
wait. His blood tests showed extremely low levels of the
virus, and all but one of his liver enzyme readings were
normal.
"I just wanted it gone," says Kee, 46, a longtime
member of the Philadelphia Fire Department.
A few months later he began a 48-week course of ribavirin
and interferon, antiviral medications that are the standard,
though often ineffective, hepatitis C treatment. Every morning
and evening he had to swallow three ribavirin pills, and three
times a week his wife injected him with interferon. The
treatment left him feeling perpetually ill, and deeply
depressed.
"It wasn't too bad in the beginning, but it got to be
hell," Kee says. "You can't sleep, you can't relax,
you feel like you have a bad flu off and on. I didn't know
what depression was until I was on this treatment. It was the
worst year of my life."
Ineffective Therapy
The combination therapy devastates most people, says
Leonard Seeff, MD, a pioneering hepatitis researcher now at
the National Institutes of Diabetes and Digestive and Kidney
Diseases. And as if the ordeal weren't bad enough, more than
half of patients aren't virus-free when it's over. Kee was
fortunate; his hepatitis C is currently in remission.
While hepatitis C can be fatal if it progresses and causes
liver disease, many infected people can go all their lives
without symptoms. And since the only available treatment can
take such a toll, doctors look at several variables to decide
whether, when, and how to treat someone who tests positive for
the virus. When lab tests show persistently elevated liver
enzymes and the presence of hepatitis C in the blood, doctors
typically order a liver biopsy to check for inflammation or
scarring. If biopsy results indicate damage, the patient is a
prime candidate for the combination therapy.
Watchful Waiting
If the biopsy is negative, what to do is less clear-cut.
But lately some experts have advised against the medication,
instead recommending regular monitoring with blood tests and
liver biopsies to see if the disease has progressed. "In
these patients, observation, including [liver enzyme]
measurements and a liver biopsy every three to five years, may
be an acceptable alternative to treatment with interferon
because progression to cirrhosis is likely to be slow, if it
occurs at all," wrote three hepatitis specialists with
the Centers for Disease Control and Prevention, Linda A.
Moyer, RN, Eric E. Mast, MD, MPH, and Miriam J. Alter, PhD, in
a January 1999, article for the journal American Family
Physician. If six to 12 months of blood tests show liver
enzymes have remained normal, they said, patients' blood could
then be tested once a year.
How well treatment works depends partly on which type of
the virus the patient has. Researchers have pinpointed three
genotypes (versions) of the hepatitis C virus. Unfortunately,
genotype 1 -- the most common form in the United States -- is
the hardest to treat successfully.
With all three genotypes, some doctors begin treatment
incrementally, using interferon alone; in those cases only 15%
to 25% of patients remain virus-free after one year. That's
not counting African-American patients, who for some reason --
researchers aren't sure why -- remain virus-free only about 5%
of the time, according to an NIH study presented in 1998
before the American Association for the Study of Liver
Diseases. Black Americans also progress much more slowly to
end-stage liver disease than people of other races. The
combination therapy is slightly more effective against
genotype 1, with a 30% success rate (again except for
African-American patients, who respond more poorly). "The
response rate is low, but it is getting better," says
Seeff.
Patients generally are treated with the combination therapy
for six months, then retested. If blood tests show no
hepatitis C, those with genotype 1 stay on the regimen another
six months to increase the odds of successful remission. But
if the virus is still present, doctors usually decide the
treatment isn't working and discontinue it.
Hope for the Future
Scientists do hold out hope, however, as they continue to
research new and improved weapons against hepatitis C. One
promising drug in development is pegylated interferon, which
is less readily excreted from the kidneys than the interferon
now in use, so it remains at consistently higher levels in the
blood. That means patients will need to be injected only once
a week, which may make treatment more physically and
psychologically tolerable.
Preliminary data suggest pegylated interferon, used with
ribavirin, can be just as helpful as the current combination
treatment -- possibly even 10% to 15% more effective, says
Seeff.
The ideal solution would probably be a vaccine, so that
everyone could be protected against this mysterious and
insidious disease. But experts don't expect to have one
anytime soon. "The virus undergoes mutations," Seeff
says. And it mutates so quickly that an inoculation given
today wouldn't work against an evolved strain a few years
later. "There may be other ways of dealing with hepatitis
C" still to discover, he says. "But there is no
conventional vaccine on the horizon."
